ServiceBus的Azure ARM模板：无法引用自身

我编写了一个ARM模板来编写ServiceBus的部署和配置脚本。脚本的目标之一是使管理主题和订阅变得容易。为了实现这一点，脚本使用数组变量

这一切都很好，但每当我尝试为两个不同的主题使用相同的订阅名称时，我就会发现一个问题。现在，我了解到订阅只能映射到单个主题。脚本试图通过将订阅名称加入主题来说明这一点

我还应该注意，Azure UI将允许您在两个主题下使用相同的订阅名称。此脚本源自通过azure控制台设置此场景，然后导出ARM

我已经看过这个剧本几十次了，但我不知道原因。希望新的眼睛会有所帮助

以下是脚本：

在执行时：

问题是由“sbSubscriptions”数组（mysubB/mytopic3）中的第三个条目引起的。这是在“资源”下的第三个对象中处理的

如果有人能看到我的疏忽，我将不胜感激

另外，如果有人知道如何让Azure工具在扩展了“复制”节点和函数（resourceId、concat）后输出模板json，那也会很有帮助

您还可以使用此选项进行调试：

Test-AzureRmResourceGroupDeployment -verbose or -debug

---

尝试

Test AzureRmResourceGroupDeployment-verbose

或

-debug

，它将向您显示（很可能）谢谢。带有-debug的TestAzureRMResourceGroupDeployment确实显示了扩展的模板。我到处寻找那个命令。我能够使用你的模板并使它工作。您提供的模板运行正常，但不完全符合我的要求。对于每个订阅，它实际上为每个主题创建一个dependsOn条目。但是，您的模板所暴露的是，我的问题的来源是在订阅的“复制”对象上指定的“模式”和“批大小”属性。移除这些，解决了我的问题。另外，感谢您在我使用变量时发现了一些疏忽。我将发布一个工作模板作为对原始消息的更新，因为它不适合这里。您还将区域硬编码放在一个位置，api版本也硬编码：）
